EPS(Expandable Polystyrene) is a lightweight, rigid, plastic foam insulation material produced from solid particles of polystyrene. Expandsion is achieved by virtue of small amounts of pentane gas dissolved into the polystyrene base material during production.The gas expands under the action of heat, applied as steam, to form perfectly clesed cells of EPS.
Expandable polystyrene is white or colorless transparent beads with a certain particle size and a relative density of 1.05~1.06. It can be colored arbitrarily and has good chemical properties. Expandable polystyrene containing low-boiling hydrocarbon foaming agent can increase its volume by 5-50 times when heated to 90-110℃, and become heat-insulating, sound-insulating, shock-proof, water-resistant, acid-resistant, and alkali-resistant And other characteristics of foam. The performance of polystyrene foam has a great relationship with the micropore structure, and is related to modifiers and additives. If the flame retardant hexabromocyclododecane is added, the foam produced has flame retardant properties.
